Description

The battery case of the lead-acid battery that a kind of electrical salf-walking is automobile-used
Technical field
The utility model relates to electric bicycle technical field, particularly relates to the battery case of the automobile-used lead-acid battery of a kind of electrical salf-walking.
Background technology
At present, along with social high speed development, the mankind's environmental consciousness is constantly strengthened, and the novel environment friendly vehicles that the electric bicycle of take is representative are accepted by people gradually; As everyone knows, traditional electric bicycle adopts lithium battery, lead-acid battery, Ni-MH battery, nickel-cadmium cell, poly-lithium battery, zinc and air cell, fuel cell etc. as storage battery mostly; In the middle of these storage batterys, because lead-acid battery has cheaply, material easily obtains, high reliability, therefore in electric bicycle field, has obtained a large amount of application; At present, adopting lead-acid battery as aspect the electric bicycle of power source, because the power supply capacity of monolithic lead-acid battery cannot meet the demand of electric bicycle to electric energy, therefore people need to will be loaded on after the series connection of polylith lead-acid battery or parallel connection in a battery case for electric motor car, the battery case of traditional electrical motor-car; But find by practice, there is following defect in existing battery case: one, because the battery case in conventional batteries box is mostly rectangular configuration, in order to prevent the setup error of battery plus-negative plate, people make the mark of both positive and negative polarity through the end of the battery case of being everlasting, therefore in use, first people need to differentiate the both positive and negative polarity that battery is installed, and then carry out laying of battery, so it is evident that: this traditional scheme needs people to identify like clockwork the both positive and negative polarity that battery is installed; Operating process is cumbersome, has certain misuse rate simultaneously; Two, for the ease of the installation of lead-acid battery, the battery case of conventional batteries box is generally slightly larger than lead-acid battery; Its result causes the lead-acid battery in battery case easily to shake, and then causes the friction between binding post, and other faults such as be very easily short-circuited; Three, due to polylith lead-acid battery being installed in battery case, often need to connect or parallel connection, therefore in battery case, just there are many and connect wires, due to the limited space in battery case, so extruding, friction, intersection between frequent generation circuit; So easily produce some unnecessary potential safety hazards; Four, traditional battery case is divided into upper shell and lower house, on two housings, is laid with circuit, so when two shell bodies engage or are fixedly connected with, the phenomenon that loose contact between two shells often can occur occurs.
Utility model content
The technical problems to be solved in the utility model is: the battery case that the automobile-used lead-acid battery of electrical salf-walking that a kind of coefficient of safety is high is provided.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
A battery case for the lead-acid battery that electrical salf-walking is automobile-used, at the bottom of comprising box and lid; In at the bottom of described box, be provided with the battery case of a plurality of placement lead-acid batteries, on inwall at the bottom of the box of described lead-acid battery end, be provided with the boss of spacing use.
Preferably, the utility model has also adopted following technical characterictic in effect:
Lid inwall in described lead-acid battery end is provided with " L " shape sponge.
At the two ends of each battery case, be respectively equipped with the side muscle that two fixed lines are used, described side muscle is fixedly connected with the inside of battery case.
Outside at the bottom of described box is provided with the quick line card that fixed line is used.
On the surface-mounted integrated circuit of described battery case is arranged at the bottom of described box.
At the top of described battery case, be provided with and be convenient to the apical pore that gas in battery case is discharged, at the sidewall of described battery case, be provided with and be convenient to the side opening that in battery case, gas is discharged.
At the bottom of described box and the corresponding position at lid top be provided with the semicircle orifice of mutual coupling, described apical pore by box at the bottom of and two semicircle orifices at lid top form; At the bottom of described box and the corresponding position of cover side wall be provided with the semicircle orifice of mutual coupling, described side opening by box at the bottom of and two semicircle orifices of cover side wall form.
In the bottom of described battery case, be provided with and be convenient to the bottom outlet that in battery case, liquid is discharged.
At the bottom of described box and the corresponding position of lid bottom be provided with the semicircle orifice of mutual coupling, described bottom outlet by box at the bottom of and two semicircle orifices of lid bottom form.
Advantage and the good effect that the utlity model has are:
One, because the utility model is provided with the boss of spacing use on inwall at the bottom of the box of lead-acid battery end, therefore when lead-acid battery side direction or swing to while being placed in battery case, existence due to boss, lead-acid battery cannot be placed into battery case, therefore can prevent well the side direction of lead-acid battery or swing to placement;
Two,, because the lid inwall in lead-acid battery end is provided with " L " shape sponge, therefore, after the assembling of lead-acid battery box, under the squeezing action power of " L " shape sponge, can well prevent that lead-acid battery from shaking;
Three, due to the side muscle that is provided with fixed line uses in battery case, the wire that therefore both positive and negative polarity can be drawn is fixed on different side muscle, so just can prevent well extruding, friction, the cross-cutting issue between wire, the coefficient of safety of raising battery case;
Four, due on surface-mounted integrated circuit being arranged at the bottom of box, the unsettled defect of wiring that therefore can avoid circuit to be installed on producing on two shells.
Five, because the utility model is provided with at top and the sidewall of battery case apical pore and the side opening that exhaust is used, therefore, can in time the combustible gas in battery case be evacuated away, prevent gathering of fuel gas, simultaneously, because apical pore and side opening form by two semicircle orifices, be therefore convenient to the processing of mould.
Six, because the utility model is provided with in the bottom of battery case the bottom outlet that draining is used, therefore can in time rainwater or other liquid be discharged to battery case, prevent the short circuit being caused by rainwater or liquid.
